Abstract: A general Brusselator system with Neumann boundary condition is considered.By the means of the stability theorem,the stability of constant solution of the model is discussed.Taking the diffusion coefficient [θ] of [u] as the parameter,the local and global bifurcation from the unique constant solution are studied by the theorems of bifurcation.The sufficient conditions for existence of bifurcating solutions of the system and its trend are obtained.

Key words: brusselator model, stability, bifurcation

摘要: 研究了一般Brusselator系统在Neumann边界条件下解的性质。利用稳定性理论讨论了其常数解的稳定性。以u的扩散系数θ为分歧参数,利用分歧理论分析了由常数解产生的局部和全局分歧情况,给出了局部分歧解存在的充分条件以及分歧解的全局走向。
